この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。

 30.000mg/ml (79.74mM) Taking the 1 mL working solution as an example, add 300 μL of 100 mg/ml clarified propylene glycol stock solution to 50 μL of Tween 80, mix evenly to clarify it; then continue to add 650 μL of D5W to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 WHI-P154 is a potent JAK3 inhibitor with IC50 of 1.8 μM, no activity against JAK1 or JAK2, also inhibits EGFR, Src, Abl, VEGFR and MAPK, prevents Stat3, but not Stat5 phosphorylation.
in vitro WHI-P154 is first described as a JAK3 inhibitor that displays no activity at JAK1 or JAK2. This compound inhibits STAT1 activation, iNOS expression and NO production in macrophages in vitro. But it is proved that this chemical also inhibits other common kinases including EGFR, Src, Abl, VEGFR, MAPK and PI3-K and induces apoptosis in human glioblastoma cell lines. [1] It inhibits glioblastoma cell adhesion and migration in the context of ECM.[2] This compound exhibits significant cytotoxicity against U373 and U87 human glioblastoma cell lines, causing apoptotic cell death at micromolar concentrations. The in vitro antiglioblastoma activity of this chemical is amplified > 200-fold and rendered selective by conjugation to recombinant human epidermal growth factor (EGF). In vitro treatment with EGF-P154 results killing of glioblastoma cells at nanomolar concentrations with an IC50 of 813 nM, whereas no cytotoxicity against EGF-R-negative leukemia cellsis observed, even at concentrations as high as 100 mM.[3]
in vivo The in vivo administration of EGF-P154 results in delayed tumor progression and improved tumor-free survival in a severe combined immunodeficient mouse glioblastoma xenograft model. Whereas none of the control mice remain alive tumor-free beyond 33 days (median tumor-free survival, 19 days) and all control mice have tumors that rapidly progress to reach an average size of > 500 mm3 by 58 days, 40% of mice treated for 10 consecutive days with 1 mg/kg/day this compound remain alive and free of detectable tumors for more than 58 days with a median tumor-free survival of 40 days. The tumors developing in the remaining 60% of the mice never reache a size > 50 mm3.[3]

キナーゼアッセイ Kinase assays
WHI-P154 is tested in kinase assays. The panel of kinases is selected to broadly cover the kinome, providing a good approximation of specificity. For all kinases, recombinant rat (IKKβ) or human (all others), full-length or GST-kinase domain fusion proteins, are used. This compound is inactive (concentration that inhibits response by 50% [IC50] > 30 μM) for the following kinases: AKT, AuroraA, cdk2, cdk6, CHK1, FGFR1, GSK3b, IKKb, IKKi, INSR, MAPK1, MAPKAP-K2, MASK, MET, PAK4, PDK1, PKCb, ROCK1, TaoK3, TrkA.
細胞アッセイ 細胞株 U87, U737
濃度 0.1-250 μM
反応時間 24-36 h
実験の流れ Cells are seeded into a 96-well plate at a density of 2.5×104 cells/well and incubated for 36 h at 37 ℃ before drug exposure. On the day of treatment, culture medium is carefully aspirated from the wells and replaced with fresh medium containing the quinazoline compounds WHI-P154 at concentrations ranging from 0.1 μM to 250 μM. Triplicate wells are used for each treatment. The cells are incubated with this compound for 24hours to 36hours at 37 ℃ in a humidified 5% CO2 atmosphere. To each well, 10 μL of MTT (final concentration, 0.5 mg/mL) is added, and the plate are incubated at 37 ℃ for 4 h. Than solubilized overnight at 37 ℃ in a solution containing 10% SDS in 0.01 M HCL. The absorbance of each well is measured in a microplate reader at 570 nm.
